>> eaton is located directly across from windsor castle. it's walking distance. so granny could keep her eye on william at eaton, and she did. so he had a sense of responsibility, always has. for william, he changed too with the death of his mother. >> changed, says anderson, without the kind, nurturing guidance diana had always provided. >> he said when he becomes king, i want william to lead from the heart, not the head. she resented the royal family. she felt they were cold and out of touch with normal people. and when she died, william and harry were cut off from diana's family and her friends and they were in a sense windsorized. all of a sudden he's fox hunting, playing polo. >> william was steeped in the ways of the windsor, but that would not keep him from small acts of rebellion, like enrolling at st. andrews instead of cambridge or oxford.
